RIGID BEDSTEAID.

Specification of Letters Patent.

Patented Sept. 23, 1919.

To all whom it may concern:

Be it known that I, LANVILLE A. BROWN, a citizen of the United States, and a resident of Kansas City, in the county of J ackson and State of Missouri,-have invented certain new and useful Improvements in Rigid Bedsteads, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to bed .steads for supporting beds and seeks to provide a simple and efficient form of bed stead that will stand rigid and support the bed in a manner that will eliminate horizontal movement of the springs with reference to the on the floor engaging supporting floor engaging supporting posts.

It is esential in the sick room and hospital that the bedstead, supporting the patient shall stand rigidly so that the springs will not move horizontally with reference to the floor engaging supporting posts of the bed stead, as any movement of the bed excepting that allowed by the resiliency of the springs often results in great pain and suffering of the patient. Excessive resiliency of the springs near the center thereof which is usually caused by the springing of the end supporting frame members is also very objectionable as it compels the occupant to either lie over the center of the springs or on an incline requiring constant resistance to prevent slippage to the center.

The present invention seeks to provide an improved bedstead that will stand rigidly legs together with a stiffening means ongitudinally of the springs to secure a regular resiliency transversely thereof.

With these and other objects in view the invention consists in the combinations, arrangements and constructions of parts hereinafter set forth and more particularly pointed out in the appended claim.

In the drawings Figure 1 is a perspective view of the bedstead with a portion of the springs broken away to illustrate the improvements thereon. r

Fig. 2 is an enlarged view in elevation of the corner connection and a portion of the adjoining pieces with certain parts broken away to illustrate the rigid connections.

Fig. 3 is an enlarged fragmentary sectional view taken on line aa of Fig. 2.

Fig. 4: is an enlarged fragmentary view with certain parts broken away.

Fig. 5 is an enlarged fragmentary sectional view, taken on line b?) of Fig. 4.

The head and foot pieces 1 and 2 respectively are of ordinary construction, there being secured thereto by the bolts 5 and nuts 6, the corner sockets 3 and the stay braces 4, the corner sockets fitting closely against the head and foot pieces and the braces fitting close to the corner sockets so thatthe bolts may draw the parts tightly together and make a rigid connection.

The corner sockets 3 are provided with the vertically slotted openings 7 the side 7 of which is concaved vertically while the side 7 is convex in the same direction, the slot being adapted to receive the wedge shaped ends 8 of the corner connecting members 9.

The flanges 13 of the corner connecting members are preferably secured to the angle shaped end members 14 by rivets 15, the holes 16 being provided in the end members to receive the bed springs 17, the latter being of the ordinary construction. Bosses 18 integral with the flanges 13 are provided to receive the ends 10 of the rods 19 thereby connecting the end members 14: together and forming a frame for the springs 17.

The center connecting members '20 are riveted to each of the end members near the center of the length thereof and extend downwardly and have the boss 21 formed on the lower end thereof which are adapted to receive the ends 11 of the rod 22 which is secured in the bosses 21 by the bolts 23 and nuts 24, the head of the bolt 27 being secured in the hollow rod 22 by lead 25 poured while melted around the head and body of the bolts, anchoring them in the holes 26 which are formed in opposite sides of the rod.

WVhen the rod 22 and connecting memhere 20 are attached to the springs they increase the strength thereof preventing the end members from bending or springing near the middle of their length and also pre-- vents one end member of the frame of the springs from twisting out of alinement with the opposite end member thereby roducing a very rigid and dependable ed for invalids with just sufficient resiliency to feel soft to the patient, and with all the swinging from side to side and vibrations that cause pain, eliminated.

The corner connecting members 9' and center connecting members 20 are preferably cast in the desired shape as shown and in connection with the hollow rods or pipes 19 and 22 form very efficient and inexpensive means of connecting the end members 14, the result being a rigid frame for the springs 17 as stiff longitudinally near the center as at either side of the frame, and the entire frame and the springs connected so that in handling they are practically integral, thus in connection with the head piece 1 and foot piece 2 forming a three piece bed which is very desirable from the fact that the springs and spring frame are rigidly connected. v

One very great advantage of the connecting members 20 and connecting rod 22 is the rigid alinement thereby of the end members 14:, so that if one corner is raised the entire end is simultaneously lifted, it having been found that spring frames of this character without the rod 22 would be pulled out of alinement by the springs and one corner thereof would rise or fall out of alinement to the extent of lifting the head piece or foot piece out of alinement so that the bed would rest on the floor in but three places instead of four as it should; It is obvious that these results were very unsatisfactory and that the improved form of bedstead overcomes these objections.

What I claim as new, and desire to secure by Letters Patent, is

In a bed-stead, a head piece, a foot piece, a spring frame detachably connecting said head piece and said foot piece, suitable springs in said spring frame, said spring frame including a transverse end member at each end thereof, a connecting member fixedly secured to each of said transverse members near the center of the length there of and extending downwardly, a hollow boss integral with each of said connecting members, an internal shoulder near the outer end of each of said bosses, a rod with each end thereof fitting within one of said bosses and against the respective shoulder, a threaded end of said rod protruding be yond each of said shoulders, and a nut on each of said threaded ends.

In testimony whereof I afiix my signature in the presence of two witnesses.
